22-7 config dhcp_relay option_60 state
Description
This command is used to decide whether DHCP relay will process the DHCP Option 60 or not.
When Option 60 is enabled, if the packet does not have Option 60, then the relay servers cannot
be determined based on Option 60. The relay servers will be determined based on either Option
61 or per IPIF configured servers.
Format
config dhcp_relay option_60 state [enable | disable]
Parameters
enable - Specifies to enable the DHCP relay function to use option 60 rules to relay DHCP
packets.
disable - Specifies to disable the DHCP relay function from using option 60 rules to relay DHCP
packets.
Restrictions
Only Administrators, Operators and Power-Users can issue this command.
Example
To configure the DHCP Option 60 state:
DGS-3620-28PC:admin#config dhcp_relay option_60 state enable
Command: config dhcp_relay option_60 state enable
Success.
DGS-3620-28PC:admin#
22-8 config dhcp_relay option_61 add
Description
This command adds a rule to determine the relay server based on Option 61. The match rule can
be based on either MAC address or a user-specified string. Only one relay server can be specified
for a MAC address or a string. If relay servers are determined based on Option 60, and one relay
server is determined based on Option 61, the final relay servers will be the union of these two sets
of the servers.
Format
config dhcp_relay option_61 add [mac_address <macaddr> | string <desc_long 255>] [relay
<ipaddr> | drop]
Parameters
mac_address - Specifies the client's client-ID, which is the hardware address of the client.
